About pig manure management

I had the same problem five years ago. I bought a farm manure separator (https://www.zhehanfilter.com/solid-liquid-separator/manure-separator.html) and now I'm working with a flower company. I separate farm manure into dry manure and send it to the flower company, which will process it into fertilizer.

The separator is an excellent tool, the centrifuge even more (http://www.getech.it/) allows you to have a good liquid fraction for fertigation and a solid part as soil improver.
